About this document
Product description
The TLD6098-1EP is an AEC qualified DC-DC boost controller, especially designed to drive LEDs. It embeds:
•
Built-in diagnosis and protection features
•
Pulse width modulator to implement a dimming function with reduced color shifting
•
Coded faults to easily detect the root cause of load failures
•
Voltage loop availability to implement constant output voltage power supply
The device also incorporates a spread spectrum modulator to reduce the electromagnetic emissions outside
the allowed bands.
Scope and purpose
The scope of this user guide is to provide instructions on the use of TLD6098-1SEPIC_EVAL.
Intended audience
Hardware engineers, software engineers, system architects
Evaluation board
This board is to be used during the design-in process for evaluating and measuring characteristic curves, and
for checking datasheet specifications.

Page 5: The Board At A Glance
TLD6098-1SEPIC_EVAL User guide The board at a glance The board at a glance TLD6098-1SEPIC_EVAL is a PCB board designed to supply high power LED with TLD6098-1EP in SEPIC topology. In this configuration, the board can deliver up to 25 W. Auxiliary circuits, to protect the DC-DC and the load during the short to ground failure, are present and enabled. -
Page 6: Scope Of Supply
TLD6098-1SEPIC_EVAL User guide The board at a glance Scope of supply The jumpers are positioned as follows: Table 3 Jumper position Jumper Number Condition Meaning Open PWM adjustment disabled Close 2-3 Internal biased to provide DC = 100% External dimming disabled Open Output current analog adjustment disabled The default configuration is depicted below. -
Page 7: System And Functional Description
TLD6098-1SEPIC_EVAL User guide System and functional description System and functional description Current adjustment The output current adjustment is performed by adjusting the value of trimmer R14. The feature is enabled when the jumper X10 is closed. The output current can vary from 0% to 100% of the maximum output current. Jumpers are positioned as follows: Table 4 Jumper position... -
Page 8: Embedded Pwm Engine
TLD6098-1SEPIC_EVAL User guide System and functional description Embedded PWM engine The embedded PWM engine provides an internal PWM signal without any external dimming signal required. To enable the feature the jumper XDC is closed. RDC trimmer adjusts the dimming duty cycle by changing the voltage on the respective DC/PWMI pin. The PWM dimming frequency is set to 410 Hz. -
Page 9: External Dimming And Output Adjustment
TLD6098-1SEPIC_EVAL User guide System and functional description External dimming and output adjustment The analog output adjustment and the dimming signals can be provided by external sources. To enable the control from external sources the jumpers are positioned as follows: Table 6 Jumper position Jumper Number Condition... -
Page 10: Faults
TLD6098-1SEPIC_EVAL User guide Faults The system has been designed to use hard threshold for overvoltage detection. With this option, once the threshold is reached, the gate driver is disabled until the output voltage goes below the reset threshold. This behavior is selected with a resistor on FPWM/FAULT pin in range 18 kΩ to 90 kΩ. In this case each fault type is reported by the FPWM/FAULT pin with a dedicated PWM waveform. -
